NirnD STATES PATENT Orrin CONGEALER FOR CAND-IOES.

SPECIFICATION forming part of Letters Patent No. 537,522, dated April 16, 1895.

Application filed Tune 20, 1894.

To all whom it may concern:

Be it known that I, HERMAN W. BEOHT, a citizen of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Congealer for Candies; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention beingcalled to the accompanying drawings, with the reference-numerals marked thereon, which form a part of this specification.

This invention relates to devices for finishing candies, chocolate-drops and similar confections where such finishing consists of hardening by congelation.

This class of candies is usually soft while and after being formed and is hardened byV ing its operation so as to economize as much as possible in the cold-producing agent.

This invention consists therefore of an endless carrier, upon one end of which the candy is formed and -whereby it is immediately carried into and through a cooling chamber with sliding doors, said carrier and sliding doors being operated together by a mechanism which is specifically constructed for the purpose and which is described and pointed out in the following specification and claim, together with its operation, parts and construction the latter being also illustrated in the accompanying drawings, in Which-` Figure 1, is a side-elevation of the device complete. Fig. 2, is a longitudinal section thereof.

and Fig. 4, is an enlarged rear-view of pawl 41 and accessory parts.

diation and excludethe influence of the outer warmer air upon its interior. The interior of this chamber may be cooled in any of the well-known Ways. It may be by a coil of pipes placed therein and carrying a cooling medium produced by a refrigerating machine, or it may be by the direct action of ice placed inside as shown in the drawings. In thislat ter case the ice rests upon a rack 7, placed above a drip-pan 8, which latter is supported above the chamber floor on cross-pieces 9. This rdrip-pan is smaller as to length and width than the same interior dimensions of the cooling-chamber, whereby a space 10 is produced all around the drip-pan over which the cold-air may pass downwardly. Additional air-passages 11 are provided in the bottom of the drip-pan to further facilitate the admission of cold-air to the space below it.

The drip of the melting ice passes out through a pipe 12. iently placed inside from above, for which purpose the top forms a door and is hinged to one of the sides. In the opposite ends of the chamber and directly above the floor thereof are openings closed by sliding doors 13, moving,when opening or closing, in guides 14:. The ends of the chamber-Hoor are eX- tended beyond these doors in the shape of shelves 15 and 16 at the outer ends of which guide-rollers 17 and 18 are supported. and around and over all of which, that is chamber-floor andV extensions thereof, an endless belt orcarrier 19 passes. This'latter should be of a material having a glazed or noin-ab sorbent surface like oil-cloth for instance with the smooth or glazed side up or outwardly which is a very suitable material.

During the normal condition doors 13 remain closed, resting directly upon the endless carrier and the candy is formed, or if choco` late-drops, they are dipped upon one of the shelves, l5 in this case, and after formed or dipped they are placed in rows upon the endless carrier and upon that part of it WhicheX-` tends beyond and from under the Wdoor and as close to the latter as possible. If a suitable number, one or more rows have been placed upon the carrier, doors 13 are opened, the carrier moves and advances the candy thereon into chamber 6, after which the former stops and the doors close, the movement The ice is most conven being simply sufficient to bring that particular batch of candy inside. Another batch is formed outside and carried in, in the same manner, which operation is repeated untilin due time finished candy appears at the other door and on shelf 16, after which the operation becomes continuous and the discharge corresponds to the feed.

As will b'e seen no extra handling intervenes after the forming of the candy and between its entrance to the coolingchamber and this entrance follows as intermediate and direct after the forming, as it is possible with any means. This sudden exposure to the chilling action of the cold air also produces a superior and glossy finish.

Owing to the continuance of the operation, the discharge of 'finished candy, after the length of the carrier inside of chamber 6, is filled once, is equally continuous and the cooling-process practically consumes no time, because finished candy appears at the discharge-end in equal proportions to the candy which is formed or dipped at theinletend.

The finished candy may be taken off of shelf 16 for packing as fast as it appears, or

when immediate packing is no object, the same may pass on until reaching the end of the upper part of the carrier, where the same returns around roller 18,'at which point the candy readily drops olf. Roller 18 is preferably of small diameter, to cause the carrier to turn on a short curve around which the candy is unable to follow and whereby it becomes readily loose and disengaged, in case it should slightly adhere thereto. Theglazed surface of the carrier however prevents in most cases any adherence and the under-surface of the candy remains smooth and even.

The width of the machine', respectively of carrier 19, may be such that one or more candy-makers may work side by side on shelf 15. The mechanical means tol be presently described, for opening the doors and advancing the carrier, operate simultaneously, in

this manner however, that the opening of theA doors slightly precedes the start of the carrier, the advance of which latter correspondingly ceases again slightly before the closing of the doors. The doors are opened by means of a treadle 20, operated by one ofthe candymakers working at shelf l5, and which treadle on depressing and by means of a pin 21, acts' upon a bended lever 22, connected by links 23 and 24, to levers25 the outerends of which lift up the swinging ends of levers 26 pivoted at 27 and thereby raise the doors by reason of their connection te levers 26 by links 28.

The carrier is moved by roller 17 which constitutes a driving-pulley, being rotated by means of sprocket-wheels 29 and 30, connected by chain 3l. Sprocket-wheel 30 has rigidly connected to it a ratchet-wheel 32, the two sitting loosely on a stud-shaft 33, the outer end of which carries also loosely, an arm 34 with a pawl 35 and a pin 36 which 0ccupies a slot in link 37. When the treadle is depressed this link is carried down until pin 36 reaches the upper end of the slot therein, whereupon arm 34 is also depressed and by means of pawl 35 rotates ratchet-wh eel 32 and sprocket wheel 30. The latter by means of chain 3l acts upon sprocket-wheel 29 and roller 17 and advances the carrier. It will be noticed that the depression of the treadle aects at once lever 22, whe-reas arm 34 is not affected until the degree of depression equals the length of the slot in link 37. By reason of this delay of action of the last mentioned parts, the doors will be open before the carrier starts and any obstacle in the path of the advancing candy is avoided. The opening of the doors is completed when pin 21 reaches the straight lower end 38 of lever 22 and it merely slides past thereon during the continued depression of the treadle without acting further upon lever 22. When the operation of the treadle and the advance of the carrier stops, the doors are held still open and remain so until the returning treadle has carried pin 21 above the straight part 38 of lever 22 whereupon the latter becomes free and is permitted with the other parts, to assume normal positions. This return in case of the doors is accomplished by gravitation while with reference to the other parts, springs l39 and 40 are used. 41 is another vpawl with a fixed center and when engaged with ratchet-wheel 42, also rigidly secured to sprocket-wheel 30, forms therewith a stop to the rotation of the rollers, primari'ly. of roller 17, and prevents belt 19 from being carrie-d beyond the intended distance 4by the impetus received from the forward motion. Part of pawl 41,in front of ratchetwheel 42 is extended and rests in a notch 43 in the laterally extended hub of arm 34 whereby said hub, when arm 34 starts to turn, acts upon the extension of pawl 41 and lifts the same out of ratchet-wheel 42 so as to permit sprocket wheel 30 to rotate. It is held in such disengagement, resting on said hub, until arm 3-4 returns to its normal position, whereupon it drops again into notch 43 and thereby lowers pawl 4l, into ratchet-wheel 42 to enable it to arrest the further rotation of the sprocket-wheels, rollers and progress of the carrier. The bearings for roller 18 are formed by adjustable boxes 44 whereby the tension of carrier 19 may be regulated and excessivesla'ek' taken out of it.

Having described my invention, I claim as new In a cong'ealer for candy, the combination of acooling chamber, sliding doors in its opposite ends, an endless carrier passing through it and through the sliding doors thereof, guide-rollers for the carrier, a treadle 20, a bent lever 22,y onefend of it capableY of operative connection with the treadle, levers 26 to which the sliding doors connect, levers 25,

for lifting levers 26, links 24 from each of the latter and link 23 connecting them to lever 22, a sprocket-wheel 29, for driving one of the guide-rollers of the carrier, another sprocket- ICS wheel 30 connected to the foriner bya chainbelt, a ratchet-whee132, on sprocket-Wheel 30, an arm 34, with a pawl 35, in engagement with ratchet-wheel 32, anda link 37, connecting arm 34 to the treadle whereby one operation of the latter acts by means of lever 22,

and link 37, in conjunction with the intermediate mechanism, upon the sliding doors
